+<tt>TCallback</tt> provides a basic callback handler that can be invoked from the
+client side by using the javascript ojbect obtained from the
+<tt>ActiveControl.Javascript</tt> property.
+You can set the <tt>CallbackParameter</tt> property from javascript directly on
+the object returned by <tt>ActiveControl.Javascript</tt>.
+Once you are ready, you can call the <tt>dispatch()<tt> method on the object to
+execute the callback.
+The server-side event <tt>OnCallback</tt> is raised when a callback is requested made.
